How to Properly Situate a Thermometer?

I'm especially interested in learning how big a difference it makes to place potted plants right up against the house. (Will the warmth of the house keep some of these plants alive through winter?)

If there is a big difference between a thermometer placed right up against the house and one placed at the far side of the backyard, it would also give me an indication that a lot of heat is escaping from the house.

In any case, I'd like to place one thermometer right against the house on the south side.
That would be in direct sunshine, which I've read is a no-no.

So, I am wondering, what is the recommended practice for getting an accurate temperature reading in a location?
Is it simply a matter of putting the thermometer in a cardboard box (to get it out of direct sunshine)?
A styrofoam box? etc.?
Any other factors to consider to ensure accurate readings at each location?

For accurate readings, try to keep the thermometer out of direct sunlight by using a well-ventilated cardboard or styrofoam box, and placing it about 4-5 feet off the ground. I can’t wait to see what insights you gain about those micro-climates around your home!
